ENTRY       EC 1.14.99.6
NAME        Acyl-[acyl-carrier-protein] desaturase
            Stearyl-ACP desaturase
CLASS       Oxidoreductases
            Acting on paired donors with incorporation of molecular oxygen
            Miscellaneous
SYSNAME     Acyl-[acyl-carrier-protein],hydrogen-donor:oxygen oxidoreductase
REACTION    Stearoyl-[acyl-carrier protein] + AH2 + O2 =
            Oleoyl-[acyl-carrier protein] + A + 2 H2O
SUBSTRATE   Stearoyl-[acyl-carrier protein]
            AH2
            O2
            Stearoyl-CoA
PRODUCT     Oleoyl-[acyl-carrier protein]
            A
            H2O
            Oleoyl-CoA
COFACTOR    Ferredoxin
COMMENT     The enzyme from safflower is specific for stearoyl-CoA; that
            from Euglena acts on derivatives of a number of long-chain fatty
            acids. Requires ferredoxin.
